E2 Levels

So I just got a call from my clinic. My E2 levels are 987 and the doctor is dropping my Follistim again. Tonight is 100 iu and tomorrow is 75iu. I wont lie I am starting to get worried,. My doctor is VERY conservative. I know that if he doesnt get this under control, they will cancel my ivf cycle. The RN told me not to be worried that they will get this where it needs to be and that I should be happy I am responding so well. She also told me I have to take into consideration that I have alot of follicles and that makes a huge difference. Jeez i am really starting to get stressed out.
